Ferric pyrophosphate CAS#10058-44-3

Excellent Solubility in Acidic Media
Readily soluble in inorganic acids, alkaline aqueous solutions and citric acid, perfectly suited for iron fortification in food and nutritional supplement formulas.
Neutral Flavor & Color Performance
It releases ferrous ions inside gastric acid without altering the original flavor or color of finished food products, greatly improving consumer palatability.
Reliable Storage Stability
The powder is slightly hygroscopic yet maintains stable physicochemical properties under regular storage conditions, adaptable to diverse industrial production processes.
Controlled Selective Solubility
Insoluble in cold water, which enables slow, targeted iron ion dissolution only in acidic surroundings and avoids premature ion release during food processing.

Ferric pyrophosphate appears as an off-yellow, odorless fine powder with a faint metallic iron taste. It dissolves rapidly in inorganic acids, alkaline solutions and citric acid, while remaining insoluble in cold water. Thanks to this unique solubility characteristic, it acts as an ideal iron fortificant for food and dietary supplements: it only dissociates iron elements under gastric acidic conditions and barely interferes with food’s natural taste and hue. Its balanced stability and selective solubility also satisfy the production demands of multiple industrial sectors that demand low moisture reactivity.
